Tension Puncture Impact
A highly accurate universal pendulum impact tester, designed in accordance with all International test standards for Izod, Charpy, Tension and Puncture impact testing of samples and components. The design utilises advanced dedicated microprocessor technology for ergonomic simplicity, ease of operation, high accuracy and repeatability of test results.
This apparatus has an energy range up to 25 Joules and infinitely variable velocity from 1.5 m/s to 3.8 m/s.
Supplied as standard with built-in test results printer, RS232 output and WindowsTM data link PC software, all included in the basic cost of the apparatus.
With the additional puncture impact feature, the system's advanced microprocessor records factual puncture test results as opposed to the traditional "drop dart" method. Welcome to the future in puncture impact testing.

Puncture Impact Feature
The apparatus is extremely versatile. Impact velocities up to 3.7 m/s combined with variable weight pendulum
hammers give an impact energy range of up to 25 Joules. WindowsTM data
link PC software provides a special impact energy diagnostic program to
assist the operator to select the correct size of pendulum hammer for the
material being tested. The test sample takes the form of a circular
clamped ring and thus eliminates any possible influence on the test
results of the way the sample is cut out.
Determining the most cost effective packaging material specification for a particular application can be a
daunting proposition if reliable information is not available on the
material behavior under different load conditions. The impact strength can
be crucial if the handling of the package cannot be controlled, especially
if objects with sharp profiles are to be packaged.
Hitherto, the principal method of evaluating the impact strength of thin ductile packaging materials has
been with a drop dart tester. But in recent years, many companies have
questioned the accuracy, reliability and repeatability of the data
obtained using this method. In the main, this is because the degree of the
material failure is so subjective to operator interpretation and
non-failures must also be accounted for in calculating the results. Also,
the absence of instrumentation providing immediate test results is a
The puncture impact feature for the Ray-Ran Advanced Universal Pendulum Impact System has addressed all of these
problems and produced a test method that is accurate, reliable and
immediately displays and prints the test result using a microprocessor
control. Test results can safely be compares between different test
centres. Therefore, an International organisation can set material
standards world-wide knowing that consistent quality control is assured.
The impact system can examine the material behavior in a combination of different ways. By using different tup
strikers, the mode of failure can be analysed to represent direct
comparisons with other materials and hence produce an in-house, or to
simulate actual service conditions.
For instance, if impact elongation properties are required for ductile material, then a large spherical
radius tup striker is used to induce a high degree of lateral elongation
of the material before the tup striker can penetrate through the material
to the point of failure. If, however, a more brittle failure (minimum
elongation of the material), a more pointed tup striker is employed. If
required, the tup striker can simulate the actual object to be packaged to
see how the packaging material would stand up to poor handling in service.
